Their existence has long been postulated from geochemical models which require multiple magma injections from staging chambers to account for their multi-scale igneous layering and variations in sources and degrees of crustal contamination. For the Bushveld Complex of southern Africa, the world's largest layered mafic intrusion, seismic receiver functions identify a diffuse crust-mantle transition beneath the Complex that suggests high velocity lower crust and/or uppermost lithospheric mantle. Here we present 3D gravity modelling of the Bushveld Complex that includes dense material at the crust-mantle boundary, imaging for the first time, remnants of magma staging chambers. They underlie the whole Bushveld Complex and extend westwards to the Molopo Farms Complex in Botswana. Feeders to the Bushveld Complex coincide with intersections of major faults like the Thabazimbi-Murchison Lineament and Sugarbush Fault with the staging chamber. This identification of magmatic staging chambers beneath the Bushveld relates to similar geophysically imaged lower crustal features beneath the Duluth and Stillwater Complexes. Comparison of seismic and gravity data with geochemical models from other complexes aid in development of models for the magmatic architecture of layered mafic intrusions in general. © 2024 Elsevier B.V.
